2017-11-10Make `rb_ast_dispose` use `RB_OBJ_WRITE`mame
This fixes the mistake of r60722. I used `rb_gc_writebarrier_remember` to notify to GC that the references is changed. But the function just adds the object to the remember set blindly. Ko1 told me that `RB_OBJ_WRITE` is suitable in this case. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60737 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-11-09node.c (dump_node): add an explanation of NODE_HASH's nd_alenmame
The field has a flag to represent if it is a keyword argument (that has no braces, e.g., `foo(k:1)`) or hash literal (that has braces, e.g., `foo({k:1})`). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60723 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-11-04Introduce `rb_code_location_t`mame
`rb_code_location_t` has two integers, lineno and column, which point to one location on a code. Now `rb_code_location_t` is used instead of `VALUE nd_location`. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60652 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-11-04Avoid usage of the magic number `(NODE*)-1`mame
This magic number has two meanings depending upon the context: * "required keyword argument (no name)" on NODE_LASGN (`def foo(x:)`) * "rest argument (no name)" on NODE_MASGN and NODE_POSTARG ('a, b, * = ary` or `a, b, *, z = ary`) To show this intention explicitly, two macros are introduced: NODE_SPECIAL_REQUIRED_KEYWORD and NODE_SPECIAL_NO_NAME_REST. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60650 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-10-31Use NODE_CASE2 if case expressions don't existyui-knk
When NODE_WHEN is compiled by iseq_compile_each0, the node passed to compile_when is NODE_WHEN (not NODE_CASE). So we can not handle the location of NODE_CASE of case statements which don't have case expressions. e.g. : ``` case; when 1; foo; when 2; bar; else baz; end ``` This commit adds NODE_CASE2, and compiles it by iseq_compile_each0. * compile.c (compile_case): Does not call COMPILE_ when NODE_CASE does not have case expressions. * compile.c (compile_case2): Compile NODE_CASE2 by compile_case2. * compile.c (compile_when): Delete an obsoleted function. * compile.c (iseq_compile_each0): Compile NODE_CASE2. * ext/objspace/objspace.c (count_nodes): Add NODE_CASE2 case. * node.c (dump_node, rb_gc_mark_node): Add NODE_CASE2 case. * node.h (node_type): Add NODE_CASE2. * node.h (NEW_CASE2): Add a macro which generates NODE_CASE2. * parse.y: Generate NODE_CASE2 if case expressions don't exist. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60585 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-10-27Manage AST NODEs out of GCmame
NODEs in AST are no longer objects managed by GC. This change will remove the restriction imposed by the GC. For example, a NODE can use more than five words (this is my primary purpose; we want to store the position data for each NODE, for coverage library), or even a NODE can have variable length (some kinds of NODEs have unused fields). To do this, however, we need more work, since Ripper still uses T_NODE objects managed by the GC. The life time of NODEs is more obvious than other kinds of objects; they are created at parsing, and they become disused immediately after compilation. This change releases all NODEs by a few `xfree`s after compilation, so performance will be improved a bit. In extreme example, `eval("x=1;" * 10000000)` runs much faster (40 sec. -> 7.8 sec. on my machine). The most important part of this change is `ast_t` struct, which has three contents: (1) NODE buffer (malloc'ed memory), (2) a reference to the root NODE, and (3) an array that contains objects that must be marked during parsing (such as literal objects). Some functions that had received `NODE*` arguments, must now receive `ast_t*`. * node.c, node.h: defines `ast_t` struct and related operations. * gc.c, internal.h: defines `imemo_ast`. * parse.y: makes `parser_params` struct have a reference to `ast_t`. Instead of `rb_node_newnode`, use `rb_ast_newnode` to create a NODE. * iseq.c, load.c, ruby.c, template/prelude.c.tmpl: modifies some functions to handle `ast_t*` instead of `NODE*`. * test/ruby/test_gc.rb: ad-hoc fix for a failed test. The test assumes GC eden is increased at startup by NODE object creation. However, this change now create no NODE object, so GC eden is not necessarily increased. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60485 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-10-24Remove dynamic NODE allocation out of parsermame
A temporary NODE object was allocated to create iseq. Instead, this patch allocates a dummy NODE as auto variable, and discard it soon. This change is intended as a preparation to manage AST NODEs out of GC. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60390 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-10-24Remove special handling for (NODE*)1mame
